Design and Simulation of Different Variants of Charging Lithium-Ion Batteries in Search for Optimum Charging Algorithm

Batteries employing Lithium-Ion technology are widely available nowadays and they are playing a crucial role in power supplies for devices ranging from mobile phones, laptops, other electronics, to electric vehicles and Battery Energy storage power systems (BESS). Hence, the performance obtained from Li-Ion batteries needs to be maximized and for that, an advanced charging strategy for Lithium-Ion batteries becomes equally important as well. This paper aims to demonstrate various charging strategies for Lithium-Ion batteries and acquire the best-suited one. Charging variants such as the Constant Voltage (CV) method, Constant Current Constant Voltage (CCCV) method, and Multistage Stage Constant Current (MSCC) method are employed as well as they are designed and simulated to obtain the best charging algorithm. Each variant is critiqued upon which can be used as a handy reference in the development of an advanced charger for Lithium-Ion batteries in the future. The main aim of an advanced Lithium-Ion battery charger is to short recharge times, obtain high charging efficiencies, and achieve an improved battery cycle life. As claimed by the experimental results, the five-stage-based MSCC charger is capable of charging the Lithium-Ion batteries with higher efficiency and taking the least time to do so, this is being selected as the optimum charging strategy,
